This is a bit tricky, but not impossible.
1. Remove the two visible screws near the bottom. 2. Pull the plastic covers off the stand: Pull from the inside (nearest where the stand is attached to the monitor. 3. Undo the screws and remove the bracket. 4. Under the bracket is the final screw. 5. Try pulling the front off the back starting at the bottom. It'll require a little force. 6. Now you should be able to get a knife in to pull the rest of the case off. Leaver by pushing the front outwards and back inwards and the clips should come off ok.

Power is ok but when i connect vga cable display not come


The monitor has faulty capacitors. Capacitors have a job to hold power long enough for your display. Faulty capacitors will only hold power for at least 2 to 8 seconds and a dead one will actually not hold power at all. The only solution is to replace the faulty capacitors. Get a computer technician to open up the monitor for you and locate the faulty, leaking, or bulged capacitors located on the circuit board where you connect the power supply. Note the polarity of the capacitors as you replace them.. (+) and (-)

Display for a few second


That is because your monitor has faulty capacitors. Capacitors in your monitor have a job to hold down power as it comes from the source long enough for a proper display. The only way to get around this problem is to open up the monitor (You can get a computer technician to do this for you if you can not do it by yourself). Or you can get a sharp - flat object and start opening (splitting) the two covers apart from the bottom of the monitor. You will notice finger-like structures that are holding the covers together. Make sure you do not break any of those. When you open it up, then check the circuit board where the power supply cable is connected. Check for any bulged or leaking capacitors. When a capacitor is bulged or leaking, it only holds power for at least 2 to 8 seconds then looses it. Buy the same type of capacitors and replace the faulty ones. Make sure you note the polarity of the capacitors before replacing (+ and -). This will definitely take you out of your trouble

Acer 2016W - When powered on, it shows colored lines (blue, green, red, yellow - vertical) and then goes to a blueish-green display color, no deskktop display at all, have tried switching out monitor...


Yep,

When the capacitors start to go out it causes the power supply to not provide the correct voltages. You monitor has the back light power but the 5v power going to the video driver board is not working correctly. Here is a link to a repair guide that will show you how to open the unit, remove the power supply board and what capacitors need to be replaced.

If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed ACER monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums

Monitor flickers and then goes blank


I had exactly this problem.
I fixed my AL2021 by replacing the output caps on the power board. $4 repair. Pull the thing apart (I posted somewhere on fixya how to do it, but it's simple) and replace the 1000uF, 680uF and 470uF caps on the end of the power board.
